The kinetic spherical model in a magnetic field

The long-time kinetics of the spherical model in an external magnetic field and below the equilibrium critical temperature is studied. The solution of the associated stochastic Langevin equation is reduced exactly to a single non-linear Volterra equation. For a sufficiently small external field, the kinetics of the magnetization-reversal transition from the metastable to the ground state is com...

Metastability in the Hamiltonian Mean Field model and Kuramoto model

We briefly discuss the state of the art on the anomalous dynamics of the Hamiltonian Mean Field model. We stress the important role of the initial conditions for understanding the microscopic nature of the intriguing metastable quasi stationary states observed in the model and the connections to Tsallis statistics and glassy dynamics. We also present new results on the existence of metastable s...

Metastability of protoneutron stars in the extended Zimanyi-Moszkowski model

We have investigated the protoneutron star (PNS) using the extended ZimanyiMoszkowski relativistic mean-…eld model of hadronic matter with and without antikaon condensation. The trapped neutrinos in PNS delay the appearance of negative-charged hadrons or K , and so its equation of state becomes rather sti¤er than neutrino-free neutron star (NS) at high baryon densities. As the results, the maxi...

We solve the dynamic equation for the kinetic spherical model that initially is in an arbitrary equilibrium state and then is left to evolve in a heat-bath with another temperature. Flows of the Renormalizational group are determined. PACS numbers: 64.60.Ht, 64.60.Cn, 05.70.Ln, 05.70.Fh

The spherical deformation model.

Miller et al. (1994) describe a model for representing spatial objects with no obvious landmarks. Each object is represented by a global translation and a normal deformation of a sphere. The normal deformation is defined via the orthonormal spherical-harmonic basis. In this paper we analyse the spherical deformation model in detail and describe how it may be used to summarize the shape of star-...
